Bleach vs. others

Hello to all,

I am starting a roof cleaning business in Indianapolis, IN. I have over 20+ year of experience in the roofing industry. I worked for many years in the technical department of the world largest manufacturer of roofing products. Over the years, I've become sick to death of working for large companies. I am now dedicated to making my own decisions, and not being at the whim of some moron in the corner office!
Thanks to all who have posted here. I cannot imagine the time, money and effort you have saved me.
Because of my skeptical nature, and the fact that my own house is going to be re-roofed over the summer, and is covered with glo-cap and moss, I tried several of the common roof cleaning methods to see what worked.

1. Pressure washing: PLEASE! The 0 degree tip does nothing. With a 25 degree tip I started at around 18" from the surface of the roof. By the time you move close enough to the shingles to get them clean, the roof is clearly damaged! This say nothing of the fact that every roof is different in composition and condition. I suppose it is possible to clean a roof that was manufactured well and is in great condition, but why would you want to take that risk when there are better methods available?

2. Shingle Saver (bought at a big box retailer). After purchasing, I read the directions. This product requires that the product be applied, wait x amount of time and then scrub with a soft bristle brush. My question is, is it the product or the scrubbing that is doing the cleaning? My guess is its the scrubbing. I could have poured bat pee on the roof and scrubbed with a brush and gotten the same results. In my opinion, any product that is advertised as a same-day cleaner and requires scrubbing is a hoax! Just to be sure, I sprayed the product on my roof and did no scrubbing. Entirely no cleaning occured. If I listened closely, I could here the glo-cap and moss laughing at this product.
3. Applesauce mixed in a fruit sprayer. Almost instant results, no problems, fast and easy. Why would you use anything else?

You do certain have to be very careful, so bleach products are not for those with little attention to detail. But for those of us who are respectful of chemicals and the property of others, this is the best method out there! The newest chlorine cowboy is saddling up and getting ready to ride!

Many roof cleaning companies follow this guideline, or a variation of it.

Since that is a EPDM roof, it can pressure washed without damaging it. Any single-ply roofing system that is not composed of asphalt (be it TPO, PVC, EPDM, etc) can be pressure washed. I would scrap off the grease first with a spade and a 5 gallon bucket. Make sure the edges of the spade are rounded to prevent puncturing the membrane.
To prevent the same build up of grease to occur in the future, there are many filter type catch basins that can be purchased. Some just build a simple pan out of steel or aluminum with a 2" lip on the sides. The pan is then filled with playground sand.

I think you may be referring to "Purple Power" by Clean-rite.

Commercial roofers use it to get single-ply roofs clean prior to making repairs.

Also, for stubborn stains on white thermoplastic roofs (TPO or PVC, etc.) the best thing to use is good old fashioned acetone. Make sure to pour the acetone on a rag fist, and then scrub.
